This is what I found.
Here is a site with a little blurb about it.http://russianfilm.blogspot.com/2010/04/pop-priest-2010.html
Then, it seems you can get a PAL DVD from Amazon, but it looks like they're out of stock at the moment...http://www.amazon.com/Pop-Priest-Russian-Soundtrack-Only/dp/B003HBCXQ8
A description about it at Kino's website:http://www.kinokultura.com/2010/30r-pop-aa.shtml
And the movie's official site, which is in Russian:http://www.pop-movie.ru/about/actions/
Hope this helps. If you're on Netflix, they have online streaming of most movies, and I don't know if they have this film in their catalog, but if you are a member there, you may want to check.
